Fees you owe, per order

GET/v1/fee-liabilities

scope wallet.read

A liability exists from the moment an order settles and is invoiced later in a batch, so this is where most of a current month lives — before any document exists. owed_amount and charged_amount differ whenever a liability settled PARTIALLY; reading one and assuming the other is how books stop balancing.

Response#

FieldTypeDescription
countintegerHow many liabilities in this page.
next_cursorstring|nullPass back as ?cursor=; null on the last page.
dataarrayWhat you owe us PER ORDER, including what has not been invoiced yet. This is the endpoint to reconcile against: an invoice is a batch of these, and a liability exists from the moment an order settles, before any document is issued.
data[].idintegerThe liability id.
data[].order_idinteger|nullWhich order it arose from.
data[].currencystringIts currency.
data[].owed_amountintegerWhat the order owed us in total — platform plus shipping fees.
data[].charged_amountintegerWhat we actually took. This DIFFERS from owed_amount whenever a liability settled only partly, and reading one while assuming the other is how books stop balancing.
data[].written_off_amountintegerThe difference we gave up rather than pursued.
data[].platform_fee_amountintegerThe commission part of what was owed.
data[].shipping_fee_amountintegerThe courier part of what was owed.
data[].statusstringpending means not yet collected. settled means we took what we could — NOT necessarily all of it, so check written_off_amount before assuming the order paid in full. cancelled follows a refund.

Accepts pending · settled · cancelled

data[].settled_atstring|nullISO-8601 UTC, or null while pending.
data[].invoiceobject|nullThe invoice this landed on, once one was issued. null means it is owed but not yet invoiced — which is exactly what GET /v1/fee-liabilities is for.
data[].invoice.seriesstringThe invoice series.
data[].invoice.numberstringThe invoice number.
data[].invoice.pdf_urlstringPath to that invoice's PDF.
